Prevalence of infectious bursal disease in local chickens around Kampala Uganda
A study was carried out to determine the prevalence of infectious bursal disease (Gumboro disease) around Kampala in the five divisions of Kawempe, Makindye, Nakawa, Rubaga and Central. A total of 400 serum samples were examined with 80 serum samples got from each division. Indirect ELISA was used. The samples were found to be reactive to antibodies against the Gumboro disease with total prevalence of 26% . A prevalence of 22.5%, 31.25%, 22.5%, 45% and 10% were got for Kawempe, Makindye, Nakawa, Rubaga and Central divisions respectively. Rubaga had the highest antibody prevalence showing that these local chickens had the highest exposure to the Gomboro viruses. The least prevalence was in Central division and may be probably due to low exposure of the local chickens to Infectious Bursal Disease (IBD) virus. The present study has shown that local free ranging chickens in the five divisions of Kampala were already exposed to IBD virus. It was recommended that further observations and studies be carried out to isolate and characterize the type of IBD virus strains circulating in these birds.
